By default only a single byte worth of identifier space is used, to minimise the overhead of the framework. You are required to keep track of the identifiers you use yourself. The Kompics part is two-fold, and consists of the se.serialization.Serializer interface, and a Serializer registration, mapping, and lookup service in se.serialization.Serializers.ДЇor every Serializer you write and register you will be required to pick a unique int identifier. With NettyNetwork comes a serialisation framework that builds on NettyвЂ™s io. Package se.sics.test import import import se. public class TAddress implements Address The examples in this tutorial require two new dependencies in the pom.xml file:

As our example program we will stick to the PingPong code from the previous tutorials and extend it with networking capabilities. The latter also features a serialisation framework, which will be described as well in this part of the tutorial. The following sections will describe the Kompics Network port, and its default implementation NettyNetwork. Instead of trying to force a one-fits-all solution onto the programmer, as systems like Akka and the venerable Java RMI do, Kompics exposes these challenges and allows system designers to find application appropriate solutions.

Network messages have to deal with unavailable nodes, connection loss, partitions, and so on. And further, and this is the second reason, it would be misleading to assume that local events and network messages have the same semantics. However, this would be very unintuitive for a programmer as it would be way too static a setup. So the logical extension of this pattern to a distributed setting would be to create cross-network channels manually.

There are two reasons for this design: First of all, events in Kompics are normally not messages in that they are not addressed, but follow channels instead. Instead Kompics requires explicit addressing of messages, that is events that (could) go over the network. As opposed to many other languages and frameworks commonly used for writing distributed applications (e.g., Erlang and Akka) in Kompics networking is not handled transparently.
